Embodiment
Below in conjunction with the drawings and specific embodiments, concrete introduction is done to the present invention.
Shown in Fig. 4, first the part in two embodiments with general character is described, body rack 2 is accessory structures that power tool body extends for installing power brick 1, power brick 1 and body rack 2 can connect and compose an entirety by relative sliding, namely power brick 1 can on first direction A insertion machine body support frame 2, it should be noted that, body rack 2 should be formed with corresponding space and go to hold power brick 1, being slidably connected between them, can be realized by similar structures such as slide rails, but be not limited thereto.Also be formed with lock hook 3 for locking to lock power brick 1, the concrete structure of lock hook 3 can see Fig. 1 and Fig. 3, and lock hook 3 also can be the hook structure that other can realize locking.
The present invention is in order to realize goal of the invention, total design is as follows, be provided with one group of locked component, wish when power brick 1 is inserted, locked component can coordinate with the lock hook 3 of power brick 1, power brick 1 is locked in primary importance, in this process, the parts being responsible in locked component coordinating with lock hook 3 should be able to dodge temporary transient lock hook 3, and then resilience realizes locking; When unblock, realize this part while avoiding lock hook 3, power brick 1 can be ejected primary importance.
In order to realize above-mentioned design concept, locked component comprises: be connected with body rack 2 by self-position change to lock hook 3 realize locking and unblock snap close piece 5, drive snap close piece 5 have actuator from the position action to locking snap close piece 5, for ordering about the unlock piece of snap close piece 5 to unlocked position action under the effect of external force; Snap close piece 5 is formed at the ejecting structure ejecting power brick 1 to unlocked position action simultaneously; Power brick 1 is formed treats roof construction for what contact for ejecting structure.
As illustrated in figs. 1 and 2, in first embodiment, actuator itself can adopt magnetic force, the multiple recovery element such as elastic force realizes, in the present embodiment, actuator is to make above-mentioned snap close piece 5 not keeping snap close piece 5 at the elastic component 4 of the state of locking lock hook 3 by trending towards during external force, specifically, in embodiment shown in Fig. 1, elastic component 4 is a helical spring, so snap close piece 5 and body rack 2 are formed in being slidably connected of second direction, the locking and unlocking is realized by moving back and forth of snap close piece 5, it should be noted that, second direction is different from above-mentioned first direction A.
See figures.1.and.2, snap close piece 5 is in order to practical function, and it is formed with slide lock bonding part 7 for contacting with lock hook 3 and for forming with actuator the fixed part 8 be connected; Slide lock bonding part 7 is formed with the snap close inclined-plane 9 tilting crossing with first direction A.
Because snap close piece 5 can not produce mobile on first direction A, so in order to eject power brick 1, power brick 1 shell formed one contact with it when snap close piece 5 unlocks eject skewback 10 as treating roof construction, pass through skewback, realize the transmission in two vertical directions, accordingly, snap close piece 5 be also formed for eject skewback 10 and contact the face that ejects 13 as ejecting structure, eject face 13 and can be parallel to first direction A.
Wherein, fixed part 8 is fixedly connected with one end of elastic component 4, the other end of elastic component 4 is fixedly connected with body rack 2, so elastic component 4 makes snap close piece 5 have the trend of right side movement in Fig. 1, order about snap close piece 5 and arrive its extreme position left always, this extreme position should be to lock the lock hook 3 that inserted, and when not inserting power brick 1, this is also the holding fix of snap close piece 5.As shown in Figure 1, when inserting power brick 1, the outside of lock hook 3 contacts with snap close inclined-plane 9, drive snap close piece 5 left side in Fig. 1 mobile, elastic component 4 is compressed, along with further insertion, lock hook 3 can not withstand snap close piece 5 again, now snap close piece 5 resilience, slide lock bonding part 7 is just in time stuck in the hook structure of lock hook 3, realizes locking; When needs unlock, force snap close piece 5 left side in Fig. 1 mobile, while lock hook 3 is exited in slide lock bonding part 7 by external force, eject face 13 and eject skewback 10 and contact, eject power brick 1 gradually, but when removing external force, snap close piece 5 recovers as before under elastic component 4 acts on to the right.
In order to better operable lock fastener 5, need to be convenient to manual unlock piece and go to realize, they both can have been formed respectively and also can be used as an overall part.In the embodiment shown in fig. 1, they are two independently parts, because snap close piece 5 is inner at body rack 2, be difficult to touch, so as preferred, unlock piece is the pull-button be slidably connected with body rack 2, and pull-button is formed to be arranged on outside body rack 2 and supplies the manual button cap 11 of people and be arranged in body rack 2 for contacting the projection 12 ordering about it and unlock with snap close piece 5.During operation, button cap 11 can provide larger contact area, and projection 12 can drive snap close piece 5 to move, and certain snap close piece 5 also should have the ledge structure coordinated with projection 12.
With reference to shown in Fig. 3 and Fig. 4, in embodiment shown in Fig. 3, snap close piece 5 on functional meaning and unlock piece are made up of same part, this part is called fit part 14, fit part 14 is formed with body rack 2 with third direction is being rotationally connected of axle, in an angle between third party and above-mentioned first direction A.This is because fit part 14 is rotationally connected with body rack 2, thus manual part is united two into one with the part ejecting power brick 1, body rack 2 is exposed as unlock piece part during normality, can be operated, when exiting power brick 1, this part be pressed turn enter body rack 2 inside realize eject.
In the embodiment shown in fig. 3, with reference to shown in Fig. 4, fit part 14 is formed with the locking cambered surface 15 and insertion inclined-plane 16 that realize snap close piece 5 function, and lock hook 3 is formed with the hook cambered surface 17 coordinated with locking cambered surface 15; The axis direction of locking cambered surface 15 is parallel with the rotor shaft direction of fit part 14, inserts inclined-plane 16 and tilts crossing with first direction A.Further, fit part 14 be formed as ejecting structure by self being forced to rotate the button 18 ejecting power brick 1, flexible member is torsion spring, treats that roof construction is the shell shell wall of power brick 1.
As shown in Figure 3, fit part 14 pins the hook cambered surface 17 of lock hook 3 by locking cambered surface 15, and due to the effect of elastic component 4 torsion spring, when not inserting power brick 1, fit part 14 is also this state.If now need to unlock, pressing button 18, fit part 14 rotates, locking cambered surface 15 produces to insertion inclined-plane 16, insertion inclined-plane 16 is now parallel with first direction A, not spacing to causing of lock hook 3, and the inner side of button 18 contacts with power brick 1 wall, along with the continuation of rotating, power brick 1 can be ejected.When inserting power brick 1, fit part 14 is identical with the state shown in Fig. 2, unlike power brick 1 not yet plug-in mounting, now inserting inclined-plane 16 tilts crossing with first direction A, therefore lock hook 3 contacts with it, and fit part 14 can be made by rotating clockwise in Fig. 3, be inserted into locking cambered surface 15 and hook cambered surface 17 dock time, fit part 14 reverses counterclockwise under the effect of torsion spring, realizes spacing on first direction A of power brick 1.
Above-described embodiment does not limit the present invention in any form, the technical scheme that the mode that all employings are equal to replacement or equivalent transformation obtains, and all drops in protection scope of the present invention.
